how do I create a serialized inventory item associated with something already sold?

AI generated answer (using internal Slack threads):

Based on the conversations, it appears that you cannot directly convert a non-serialized inventory item to a serialized inventory item in NetSuite. This is because serialized and non-serialized items are considered different item types in NetSuite. Here are the steps you can follow to create a serialized inventory item associated with something already sold: 1. Export the original item record. You can create a saved search for the items in question with all the desired fields you need and then export the results. 2. Update the existing items to Inactive. You can also rename them if it helps you differentiate between the old non-serialized items and the new serialized items. 3. Import new serialized item records using the exported data from step 1. You can use a CSV import to recreate them as serialized inventory items with minimal effort. Please note that this process will require some manual steps or custom code. Also, be aware that using serialized items will add additional processes including specifying serial numbers on receipts, fulfillments, and adjustments. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
